TEMPORARY BINDER.

Specification of Letters Patent.

Patented Sept. 12, 1905.

Application filed April 14, 1904. Serial No. 203,119.

To all whom it may concern:

Be it known that I, THOMAS R. EDDY, of Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Temporary Binders,of which the following is a specification.

This invention relates to temporary binders used for binding together inbook form a number of loose leaves, and more particularly to an improvedmeans for locking against separation the telescoping binder-posts ofsuch a binder.

Among the salient objects of the invention are to provide a simplebinder of the character referred to which can be economicallymanufactured; to provide suchabinder with a locking mechanism which willeffectively lock the telescoping binder-posts thereof together in anyposition of their movement one upon the other and with such firmnessthat they cannot be pressed together or pulled apart when locked; toprovide a locking mechanism which is applicable to the usual round postsused, thereby making it unnecessary to have specially-formedpost-tubing, and consequently lessening the cost of manufacture; toprovide a locking mechanism which is wholly within the telescopingbinder-posts, thereby leaving the edges and surfaces of the binderperfectly smooth and uniform, and in general to provide improvements indetails of construction and arrangement which produce a cheap, simple,and highly-desirable temporary binder of the characterreferred to.

To the above ends the invention consists in the matters hereinafter setforth and will be readily understood from the following description,taken with the accompanying drawings, in which- Figure 1 is a front viewof a binder embodying the invention as seen between the cover members,partly in section. Fig. 2 is a sectional view taken on line 2 2 of Fig.1 and looking in the direction of the arrows. Fig. 3 is a sectional viewof the binder-post carrying the locking mechanism and taken on line 3 3,Fig. 2; and Fig. 4 shows a key for turning the locking mechanism.

Referring to the drawings, 1 and 2 designate a pair of overlappingbinder members of angle form and provided with telescoping binder-posts3, L, and 5 and also provided with the usual cover members 6 and 7flexibly secured thereto.

The binder-post 4 in the construction shown carries the lockingmechanism for locking the binder-posts together, said locking mechanismcomprising a locking-block 8 of the same external diameter as the innertelescoping member of the binder-post and mounted at the end of saidinner telescoping member eccentrically and rigidly upon the end of abolt 9, which extends through said inner telescoping member and ismadesquare at its opposite end to receive a key by which it is turned toturn the eccentrically mounted block member 8, resting against the endof the inner telescoping member and within the outer member, as clearlyshown in the drawings. In order to confine said bolt within the innertelescoping member, said member is provided in its interior witha pair.of confining blocks or washers 10 and 11, said blocks havingtherethrough a little off of center apertures through which reducedportions of said bolt pass and which form bearings for said bolt,preventing longitudinal or lateral movement thereof and causing awedging or binding engagement between the locking-block and the outertelescoping member when the bolt is turned. By this construction saidlocking-block when in one position registers with the inner telescopingmember, at the end of which it is mounted, and moves within the outertelescoping member wit-h case, but when turned with the bolt 9, becauseof the eccentric connection therewith, it tends to move out of registerwith the inner member of the binder-post, and consequently into bindingor looking engage ment with the interior of the outer post member,thereby locking said post members against movement, one upon the other.Thus avery effective and a very simple locking mechanism is provided andone which can be easily and economically manufactured because of thefact that uniform tubing can be used without special formation oralteration.

It is obvious that modifications in the details of construction andarrangement can be made without departing from the spirit of theinvention, and I do not, therefore, limit the invention to these detailsexcept in so far as they are made the subject-matter of specific claims.

I claim- 1. In a'binder for holding loose leaves or the like, thecombination with back or cover members, of a plurality of impaling-postsmounted thereupon, one of said posts comprising a pair of telescopingmembers, of which one member slides freely within the other, a lockingmember similar in cross-sectional form and dimensions to the telescopingpart of theinner telescoping member and journaled upon the latter toextend exteriorly thereof and to rotate upon an axis eccentric to thelongitudinal axis of said inner telescoping member, and means forpositively rotating said locking member whereby to frictionally locksaid telescoping members against longitudinal separation.

2. In a binder, two telescoping members, a locking member eccentricallyand rotatably secured to and exteriorly of the inner telescoping memberand moving therewith within the outer member, and means for rotatingsaid locking member to frictionally lock said telescoping memberstogether.

3. In a binder, means for locking the two main parts thereof together,comprising two telescoping members, a locking member, similar incross-sectional form and dimensions to the telescoping part of theinnermember, and journaled upon the latter to extend exteriorly thereof andto rotate upon an axis eccentric to' the longitudinal axis of the innertelescoping member, and means for rotating said locking member to carryits outer lateral sides out of register with the inner telescopingmember and bring it into frictional engagement with the outertelescoping member.

4. In a binder, two telescoping members, a bolt eccentrically androtatably mounted in the inner telescoping member, and a locking memberrigidly and eccentrically mounted upon one end of said bolt exteriorlyof said inner telescoping member, whereby the turning of said boltoperates to turn said locking member into frictional locking position.

5. In a temporary binder, the combination with a pair of binder membersprovided with telescoping binder-posts, of a locking mechanism forlocking said binder members against movement toward and from each other,comprising a bolt eccentrically and rotatably mounted within one of saidbinderposts, a locking member rigidly and eccentrically mounted upon oneend of said bolt exteriorly of the inner member of said post, said boltbeing secured against longitudinal or lateral movement bodily,substantially as described.

6. In a temporary binder having telescoping binder-posts, a lockingmechanism for locking the telescoping members of said posts togethercomprising a bolt rotatably and eccentrically mounted within the innermember of said post, a lock-block of the same exterior diameter as saidinner member rigidly and eccentrically mounted upon the end of said boltagainst the end of said inner member and registering therewith when inone position of rotation, and means for turning said bolt to move saidlock-block eccentrically into frictional locking engagement with theinterior of the outer telescoping member, substantially as described.

7. In a temporary binder, two telescoping binder-post members, ajournal-bearing carried by the inner of said post members, a lockingmember eccentrically and rotatably mounted in said journal-bearing, saidlocking member resting adjacent said journal-bearing and cooperatingtherewith when rotated to exert expanding pressure in substantially thesame transverse plane in opposite directions within said outer postmember, and means for rotating said locking mem ber.
